' ABSORPTION APPARATUS.

To all whom it may concern:

Be it known that I, GUSTAV AMINOFF, citizen of the Grand Duchy ofFinland, residing at Baltimore. Maryland. have invented certain new anduseful Improvements in Absorption 1-\pparatus. of which the following isa specification.

My invention relates to apparatus of that class in which liquids andgases are brought into contact, whereby gas is absorbed by the liquideither to purify the gas, or to impregnate the liquid,

My invention herein explained operates .by simultaneous passage of gasand liquid in opposite directions, as in the well known apparatus inwhich a series of'bottles is used, the bottles being connected by pipes.

My said invention comprises a chute steeply inclined, and closed atsides and bottom forming a liquid and gas passageway, with a series ofboxesformed by partitions set in the upper part, but not extending tothe bottom.

It is illustrated in the accompanying drawings, in which- Figure 1 showsa longitudinal vertical section of the apparatus; and Fig. 2 a sectionon line 2-2 of Fig. 1, seen from be- -n eath. v

The main part ofmy absorber or washer is indicated at B. This consistsof a steeply inclined chute or tube having top, bottom and sides forminga channel for the passage of the gas and liquid. The upper partof thischute is subdivided into boxes 5 by partitions 4, extending from side toside and -from the top halfway, more or less, toward the bottom (3 ofthe chute. This construction, and the inclination, form a series ofclosely set boxes, in which portions of the liquid are held and exposedto the action of the gas.

At the upper end 01'' the chute is a tank 8, into which water is fedfrom a supply pipe 7. The bottom of this tank inclined, and the tank isseparated from the gas exit pipe by a wall 9, at the bottom of which isan opening through which the liquid may pass underneath the gas exitpipe, over a shoulder 17, and through a passage 10 into the upper end ofthe chute. just; below its end wall. The passage pipe 10 'is made in twoparts held separably together at. the flanges .20. The lower end of thechute is also closed, and an overflow ipe 12 for the liquid is set inthis lower end: and provided with a dis- Specification of LettersPatent."

charge branch, set at a properpoint in height, in relation to the tank8,'to maintain the liquid in the boxes of the chute. A drain pipe andfaucet are indicated at 21. Above the pipe 12, and below the series ofboxes, at gas supply pipe 13 is connected with the chute.

At the ,upper end of the chute is a gas exit pipe 16, the lower end ofwhich opens into.

the liquid passage from the tank to the. chute, so that the gas, risingtherein, can

esca e from the liquid and rise in the pipe.

Ba es, as shown in Fig. 1, are set, preferably inclined, in the pipe 16,to throw back the spray.

As it is found desirable to occasionally remove the bottom 6 forcleaning thisbottom is held to the chute removably by suitable clamps 7,using packings between the parts;

It will be observed that there is a clearpassage for the liquid beneaththe lower edges of the partition walls which form the boxes, and ,abovethe bottom of the chute. The heightof the discharge of. the liquid andthereby its surface in the tank 8 is adjusted to secure the amount 'ofhydrostatic pressure necessary to force the liquid against theresistance of the reverse gas current and through the overflow pipe. Thepartition 9, therefore, affords a seal against the escape of the gasinto the reservoir 8, and thus the flow of the liquid is automatic whilethe inflow is sealed from the gas. The apparatus being thus properlyadjusted, the gas will occupy the boxes while the liquid rises from theclear passage and presses upon it in the boxes while the outward flowinggas rises, flowing over the lower edgesof the partitions and from ne boxinto the other. The pipe 12 for the automatic overflow of liquid may beomitted, and the outflow may be 3.1 lowed to take place through thefaucet 21, this faucet being regulated to properly check the flow orliquid, and hold back suiticient for the purpose above indicated.

The combined feed box and gas discharge, with the seal, are detachableas a. whole from the chute by means of the flange joint at 20. I am alsomaking the absorption chute wider at the gas inlet end and narrower atthe gas outlet, thus providing more absorbing capacity where the volumeof gas is largest, and less where the gas has been partly absorbed andreduced in volume. These proportions may be reversed in special uses ofthe apparatus where the relations of the gas and the liquid require it.This variation in the ca ac1ty at the ends of the chute is illustrated1n Fig. 2. Also the spaces in the chute between the compartments and thebottom may advantageously be made progressively deeper from the lower tothe upper end. The proportions of the construction are varied with thevarying pressure of the incoming. and outgoing gas. The lower thepressure of the outgoing gasthe lower will be the liquid in the feedbox. If the gas is underpartial vacuum, the construction must be such asto permit theliquid level to sink accordingly in the feed box withoutbreakiugthe hydrostatic seal. If the incoming as is .at or belowatmospheric pressure, the

' iquid outflow is accordingly lowered.

This absorber may also be used when it suits the purpose withoutconstant reverse act-ion between the gas and the liquid. The liquidmaybe stationary or maybe fed and drawn-to many points by meansof'gooseneck pipes, which provide seals of liquid against the escape ofgas.

Itiwill be apparent that the apparatus may be used to wash the liquid bythe gas or the reverse. It is made of any suitable material, such assoft orhard lead, iron, earthenware, or wo'od,es-the material used 7 mayrequire. 7

I claim as my invention substantially as herein described:

1. An absorption apparatus comprising an inclined closed chuteconsisting of aseries of contiguous boxes'in its upper part, and abottom completing the liquid passage under-' neath said passagecommunicating-with the and means for introducing gas at the lowei anddischarging the same-at the upper end 2. In an absorber, an inclinedclosed chute consisting of a series of upper open boxes, 21 bottomcompleting the liquid passage, an open feed box or reservoir, :1. liquidsupply therefor, seals to prevent the escape of gas a discharge forliquid at the lower end 01 the chute, and means for passing the"gas in adirection opposite to the fiow of tl1( liquid. 3. The described absorbercomprising ar inclined closed chute havinga series of boxes means forfeeding the liquid and discharging the gas at the upper end of saidchute a gas inlet pipe set near the lower end 01 the series of boxes ofsaid absorber, and a liquid overflow pipe set in the lower end 01 saidchute and below the gas inlet pipe. whereby a body of liquid is ledbetween the gas inlet and the liquid discharge,'and a gas seal formed.-

4. In the described absorber, the open feed box 8, connected to thechute by a detachable joint 20, said chute having an inclined bottom anda series of-boxes, a gas. discharge pipe 16, set between the chute andthe feed box, and a partition 9 extendin near to the said bottom andforming a seaE 5. In the described absorber, an inclined chute having aseries of boxes, and means for i'mtrpduc-ing and discharging reversecurrentsof liquid and gas, the chute varying in width along thecourseaiof the same to accommodate a changing volume of gas.

In testimony whereof, I- atlix my signature in presence of twowitnesses.
